T his invention relates to pumping apparatus, and more particularly to that type of apparatus in which reciprocating pump rods, are employed.

It is among theobjects of the present inifiBYfilltmixing of the fluid being pumpe with lubricant supplied to the pump driving mechanism, or vice versa.

Further objects. and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings, wherein a preferred form of embodiment of the present invention is clearly shown.

In the drawings: Fig. 1 is a view partly in sectiono embodying the present invention.

Fig. 2 is a sectional view taken on the line 2-2 of Fig. 1.

Referring to the drawings, a gear housing 20,*wh1ch provides a lubricant chamber 21, sup orts an electric motor 30. Motor fpartly in elevation and shaft 3 provided with a worm 32, extends into the gear housing and is journalled in bearings 33 and 34 supported within said housing. A,flvwheel 35 is secured to the end of motor shaft 31 and is accessible for removal through an aperture 22 in housingJ20 which is closed by a removable cover 23.

An aperture 24 in the top of housing 20 is provided with an annular cover or frame 40 having an apertured boss or bearing 41 extending from said housing 20 through aperture 44in the top of frame 40. Frame 40 provides an annular chamber 42 surrounding bearing 41, which may be drained by connecting a suitable drain cock with opening 43 in a wall of said chamber. An

annular flange 45, on frame 40, is received within a frame 50 which is secured to frame 40 by bolts 5-1.

Frame 50 supports a pump cylinder 60, having a pump rod 61 adapted to be reciprocated within said frame 50, directly above the gear housing 20. Frame 50 is provided with openings 52 for permitting access to the pump rod 61. A substantial y cylindrical shaped frame 55 is located within frame 50 and is rotatably supported by flange on frame 40. Frame 55 may be rotated by a handle-57 for closing openings 52 in frame to prevent access to 1plump rod 61, or to bring openings 56 into a ement with opena pumping apparatus ings 52 to permit access to said pump rod. Frame is provided with openings 58 adjacent the bottom edge thereof.

it shaft 70, supported within gear housing 20 at ri ht angles to shaft 31, carries a worm gear 71 which is driven by'worm 32. An eccentric 72, carried by gear 71, is pro- "vided with an eccentric strap 73 which functions as a connecting rod for reciprocating a cross head 7 5 through apertured boss or hearing 41. Pump rod61 is secured to cross head 75, and the recip'rocatory movement of said cross head is transmittedto rod 61, to operate thepump. 1

A cup shaped member'or baffle 80, having a flange 81, is secured between the cross head 75 and the pump rod 61 and is adapted to be reciprocated within frame 55 by said rod 61. Flange 81 is adapted to extend into the chamber 42 surroundlng bearing 41, upon the downward stroke of rod 61, as clearly shown in Fig. 1.

l Mode of operation.

YVhen the motor 30 is operated, worm 32 drives worm gear 71 which in turn drives eccentric 72, and eccentric strap 73 causes cross head 75 to be reciprocated through bearing 41, and this reciprocatory movement is transmitted to the pump rod 61. At the same time, thebaflie 80 is reciprocated within frame 55 in response to the movement of the pump rod. 61. An liquid which may escape from the cylin er '60 around the pump rod 61, will trickle down rod 61 and strike baflie'SO and be deflected thereby into the chamber 42, and be prevented from working its way between cross head 75 and bearing 41 into the lubricant chamber 21. Any lubricant tending to work its way from chamber 21 between cross head 75 and hearing 41, will be deflected into chamber 42 by the inner surface of bafiie 80, which entirely surrounds the top edge of bearing 41, and

in this manner the lubricant will be prevent- 100 ed from coming into contact with the pump rod 61.

While; the form of embodiment of the present lnventlon as herein disclosed, constitutes a preferred form, it' is to be understood that other forms might be adapted, all coming within the scope of the claims which follow.

What is claimed is as, follows:

1. Pumping apparatus comprising, in" 19 combination, a pump cylinder including a pump rod; 2. gear musing; an apertured frame separating the pump cylinder and gear housing; driving mechanism Within the gear housing; means for connecting the driving mechanism, and pump rod; and batflo means carried by the pump rod so as to be on the cylinder side of the apertured frame at all times, for deflecting upon said frame fluid escaping from either the pump cylinder or the gear housing.

2. Pumping apparatus comprising, in

combination, a pump including a cylinder and pump rod; a gear housing a frame separating the pump cylinder and gear housing said frame having an apertured extension toward the cylinder; driving mechanism Within said gear housing; connecting means between the driving mechanism and pump rod; and means interposed between the pump rod and connecting means, and includ ing a portion adapted to surround the apertured extension whereby fluids escaping from either the pump or the gear housing will be deflected upon said frame and outside of the apertured extension.

3.'Pumping apparatus comprising, in combination, a pump rod, a gear housing, an apertured boss extending from said gear housing, a cross head received by said aperture for connecting the driving mechanism and pump rod, and a bafiie movable with the pump rod on the side of the apertured boss opposite the driving mechanism and vhaving a flange adapted to surround the cover for said housing providing a bearing and an annular chamber surrounding the bearing, a cross head received by said bearing for connecting the driving mechanism and pump rod, and a baffle movable with the pump rod having a flange adapted to surround the bearing and cross head and extend into the chamber for deflecting a liquid escaping from the pump around the pump rod and liquid escaping through the bear ing around the cross head into said chamber from where it may be drained.

In testimony whereof I hereto aflix my signature.

CLARENCE WARNER.
